Getting number of subscribers

There's an easy way to display number of clients watching the stream. You need to

• set up statistics page at location /stat

  location /stat { rtmp_stat all; allow 127.0.0.1; }

• create a simple xsl stylesheet nclients.xsl extracting number of stream subscribers

  <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:output method="html"/>

  <xsl:param name="app"/> <xsl:param name="name"/>

  <xsl:template match="/"> <xsl:value-of select="count(//application[name=$app]/live/stream[name=$name]/client[not(publishing) and flashver])"/> </xsl:template>

  </xsl:stylesheet>

• set up a location returning number of suscribers

  location /nclients { proxy_pass http://127.0.0.1/stat; xslt_stylesheet /www/nclients.xsl app='$arg_app' name='$arg_name'; add_header Refresh "3; $request_uri"; }

• use HTTP request http://myserver.com/nclients?app=myapp&name=mystream to get the number of stream subscribers
